The bogie for the railway wagon has following beneficial effects: at present, the light-duty bogie is lowest in self weight and distance between the core plate surface and the rail surface of the same type at home and abroad and is of considerable economic benefit and social benefit.
Description
Technical field
The utility model relates to railway transportation equipment field, is specially a kind of bogie for railway wagon.
Background technology
The effect of railway freight car bogie is prop carrier, and guided vehicle is along rail running, and bears the various loads from car body and track, is the critical component of rail freight.Domestic principal mode bogie truck is to turn k6 type bogie truck at present, the same with other bogie truck of the same type, conduct oneself with dignity all bigger than normal, and bogie truck deadweight is larger on circuit dynamic deformation from motion, framework fatigue reliability and safety in operation impact, lower bogie truck deadweight can reduce dynamic deformation from motion, and can improve vehicle load, thereby the economic benefit of significantly improving, therefore should reduce as far as possible bogie truck deadweight, existing bogie truck cartridge face height to the top of rail is higher, if suitably reduce, can reduce vehicle's center of gravity, improve vehicle operating stability.
Summary of the invention
The utility model, in order to solve the problems such as the deadweight of existing lorry bogie truck is bigger than normal, bogie truck cartridge face height to the top of rail is higher, provides a kind of bogie for railway wagon.
The utility model is to adopt following technical scheme to realize: bogie for railway wagon, comprise that front and back wheel is to, two bogie side frames, bolster, brake equipment, truck center plate, the two ends drawing strickle guide of bogie side frame is arranged on front and back wheel to upper by adapter and antifriction-bearing box, the two ends of bolster are arranged on by spring vibration damper in the bearing spring platform of bogie side frame, innovative point of the present utility model is that the interior exocoel of bolster, bogie side frame offers lightening hole, the wall thickness of bolster, bogie side frame adopt by be thinned to thick or by thick to thin even rounding off structure; Bolster one side is provided for connecting two side boss and the side through hole of brake equipment dead lever fulcrum seat, and both sides, bolster top are provided for connecting convex platform and the upper through hole of side bearing; Bolster and truck center plate are cast into integral structure.
Two medial surface belows of described side frame guide adopt little free-running fit with housing washer, can increase the diamond resistant rigidity of bogie truck and reduce deadweight.
Grit is set up in the bearing spring platform both sides of described bogie side frame, has improved bogie side frame intensity and can prevent that spring from deviating from, and for preventing bearing spring platform inner product rainwater, discharge orifice is offered in bottom.
Described bogie side frame chute outer end adopts enclosed construction, can improve the intensity at bogie side frame chute place and prevent that the brake beam of brake equipment from deviating from.
The rigid wheelbase L of described bogie truck is 1728mm, and bogie side frame middle part height H is 740mm.
bogie side framethe excessive or bogie side frame of rigid wheelbase middle part highlyer all will make bogie truck deadweight strengthen, aggravation wheeling edge wearing, simultaneously unfavorable to bogie side frame intensity, therefore, ensureing in central mounting Rational Parameters layout situation, shorten rigid wheelbase as far as possible and reduce the height at bogie side frame middle part, rigid wheelbase is defined as 1728mm, compared with turning k6 type bogie fixed wheelbase 1830mm, shorten 102mm, the height at bogie side frame middle part is defined as 740mm, compared with turning k6 type truck side frame middle part height 787, has reduced 47mm.
The beneficial effect compared with prior art having: compared with lightweight truck described in the utility model turns k6 type with domestic principal mode bogie truck, axle heavy phase is same, gauge is identical, single bogie truck weight reduction 600kg, not only reduced the dynamic deformation from motion between wheel track, and can make vehicle load improve 1.2t, have significant economic benefit, meanwhile, the free height of lightweight truck cartridge identity distance rail level has reduced 31mm, because center of gravity reduces, improve the riding quality of bogie truck.In a word, this lightweight truck is the bogie truck that the middle deadweight of domestic and international bogie truck of the same type (same axis weighs and gauge) is at present the lightest, cartridge identity distance rail level is minimum, has significant economic benefit and social benefit.

Detailed description of the invention
Bogie for railway wagon, as shown in Figure 1, 2, comprise front and back wheel to 1, two bogie side frames 2, bolster 3, brake equipment 4, truck center plate 5, the two ends drawing strickle guide 6 of bogie side frame is arranged on front and back wheel to upper by adapter 7 and antifriction-bearing box 8, the two ends of bolster are arranged on by spring vibration damper 9 in the bearing spring platform 10 of bogie side frame, the interior exocoel of bolster, bogie side frame is offered lightening hole 11, the wall thickness of bolster, bogie side frame adopt by be thinned to thick or by thick to thin even rounding off structure; As shown in Figure 3, bolster one side is provided for connecting two side boss 12 and the side through hole of brake equipment dead lever fulcrum seat, and both sides, bolster top are provided for connecting convex platform 13 and the upper through hole of side bearing; Bolster and truck center plate are cast into integral structure.As shown in Figure 4, two medial surface belows of side frame guide 6 adopt little free-running fit with antifriction-bearing box 8 outer rings, and grit 14 is set up in bearing spring platform 10 both sides of bogie side frame, and discharge orifice 15 is offered in bottom, and bogie side frame chute 16 outer ends adopt enclosed construction.
As shown in Figure 1, the rigid wheelbase L of this bogie truck is 1728mm, and bogie side frame middle part height H is 740mm.
Bolster and bogie side frame are two vital parts of bogie truck, are also the heaviest parts of weight, and in order to improve the riding quality of bogie truck and significantly to alleviate bogie truck deadweight, emphasis is optimized design to the structure of bolster and bogie side frame:
By bolster and bogie side frame are carried out to strength Calculation, to all attenuate wall thickness to some extent of the less part of all stress, to make wall thickness be no longer single-phase with thickness but thick or by honest and kind thin even rounding off by being thinned to, according to stress situation, the interior exocoel of bolster and bogie side frame is opened to the lightening hole that many size and shapes differ in addition, reached the object of maximum loss of weight.The bolster of existing bogie truck and truck center plate are two individual part, by bolt or rivet joint together, bolster and truck center plate are cast into integral structure by lightweight truck, not only avoid in the past attachment bolt or rivet cut off or looseningly lose the risk of bringing because of stressed, and effectively alleviated weight; In bolster one side, two boss and 4 through holes are set, are used for connecting the dead lever fulcrum seat of brake equipment, facilitated assembling and the maintenance of dead lever fulcrum seat; Boss and 4 through holes that supporting side bearing is set on bolster top, be used for connecting side bearing; The design quantity of the outer coil spring of bolster and interior coil spring is each 14, and wherein the concrete quantity of interior coil spring can change according to the deadweight of different automobile types is different to some extent with position.
